Question

How many atoms are in 1.204x10^22 moles of arsenic?

Answer 1

0.02 moles

Step-by-step explanation:

To find the number of moles in a substance given it's number of entities we use the formula

`n = (N)/(L) \\`

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

We have

`n = \frac{1.204 * {10}^(22) }{6.02 * {10}^(23) } \\ = 0.02`

We have the final answer as

0.02 moles
